Abstract
A three-dimensional x-ray imaging system includes at least one detector and an x-ray source including an x-ray transmissive vacuum window. The x-ray source is configured to produce diverging x-rays emerging from the vacuum window and propagating along an x-ray propagation axis extending through a region of interest of an object to the at least one detector. The diverging x-rays have propagation paths within an angular divergence angle greater than 1 degree centered on the x-ray propagation axis. The system further includes at least one sample motion stage configured to rotate the object about a rotation axis. The system further includes a sample mount configured to hold the object and comprises a first portion in the propagation paths of at least some of the diverging x-rays and having an x-ray transmission greater than 30% for x-rays having energies greater than 50% of a maximum x-ray energy of an x-ray spectrum of the diverging x-rays.
